Abstract

RODRIGUEZ-GONZALEZ, RE et al. Yield stability of wheat in the Mexicali Valley, México. Phyton (B. Aires) [online]. 2014, vol.83, n.1, pp.65-70. ISSN 1851-5657.

The aim of this study was to evaluate grain yield (RG) stability of some commercial wheat varieties, and to assess the stability of other parameters which are not typically measured for grain release purposes: performance of straw (RP), weight per hectoliter (PH), white belly (PB), harvest index (IC), grain protein (PG) and gluten strength (W). The evaluation was performed with the wheat varieties Cachanilla F-2000 (C), Yécora F-70 (Y) and Triguenio F-00 (TR), in El Valle de Mexicali, Baja California under four test environments, with the application of the Eberhart and Russell model. The study was developed during the 2010-2012 periods, using a completely randomized block experimental design with four repetitions. All genotypes qualified as stable to RG, RP, PH, IC, W and PG (β=1 and S²d_i=0). Additionally, only the genotype (Y) scored as stable to white belly.
